In the actual use process, if the grinding roller 45 is fixed, the working surface of the grinding roller 45 and the working surface of the grinding ring 46 are always unique, so that under a long-term working state, the working surface of the grinding roller 45 is worn to cause serious out-of-round deformation of the grinding roller 45, if the original grinding time is kept, calcium hydroxide particles are not ground to a qualified degree, the calcium hydroxide particles are limited by the blocking of the grading machine and cannot be led out and accumulated on the base of the tank body 1 until too many materials are stored at the bottom of the tank body 1, and in serious cases, the scraper knife 47 cannot scrape or scrape out too many materials at one time, the grinding roller 45 and the grinding ring 46 are difficult to grind into powder, and the grinding roller 45 and the grinding ring 46 are not adapted to generate large noise;
therefore, in the first state of the present invention, a circumferential rotation mechanism is designed to intermittently adjust the working surface of the grinding roller 45, in an initial state that the lifting mechanism 43 adjusts the distance between the top cover 48 and the connecting frame 42 in place during operation, the limit gear 57 extends out of the connecting frame 42 under the push of a spring to be meshed with the gear ring 51, when the adjusting motor 54 is not driven, the limit gear 57 can only slide up and down and cannot rotate, so that the gear ring 51 and the meshed external gear 52 can be limited from moving, at the moment, the grinding roller 45 rotates in the circumferential direction to be matched with the grinding ring 46 to grind powder, when a certain angle needs to be adjusted, the stepping motor 41 stops, the lifting mechanism 43 contracts until the internal gear 55 on the adjusting motor 54 just props against the limit gear 57, until the limit gear 57 is compressed into the groove 56, at the internal gear 55 is meshed with the gear ring 51, the control end controls the adjusting motor 54 to drive the connected internal gear 55 to rotate, the internal gear 55 is meshed with the gear ring 51, so as to drive the gear ring 51 to rotate by a certain angle, the gear ring 51 rotates to drive the external meshed with the gear ring 52 to drive the external meshed, so that the external gear ring 51 to rotate, the grinding roller 45 rotates by a certain angle, so that the working surface of the grinding roller 45 connected with the grinding roller 45 is automatically changed, the grinding surface of the grinding roller 45 can be adjusted, and the grinding mechanism can be adjusted, on the other hand, the grinding surface can be adjusted, and the grinding roller 45 can be adjusted, and the grinding mechanism can be reduced, and the grinding mechanism can be adapted to reduce the grinding surface of the grinding roller 45, and the grinding mechanism can be adjusted intermittently, and the grinding mechanism can be adjusted, and the grinding mechanism can be reduced, and the grinding mechanism can be adjusted intermittently adjusted, and the grinding mechanism can be adjusted;
in the second state, in the initial state that the lifting mechanism 43 adjusts the distance between the top cover 48 and the connecting frame 42 to be in place, the internal gear 55 presses the limit gear 57 into the groove 56, the internal gear 55 is meshed with the gear ring 51, the circumference exchanging mechanism 5 continuously works, and the rotation direction of the adjusting motor 54 is controlled, so that after the meshing transmission of the internal gear 55, the gear ring 51 and the external gear 52, the rotation direction of the external gear 52 and the grinding roller 45 is opposite to the circumferential rotation direction of the whole driving body of the stepping motor 41, for example: while the grinding roller 45 is driven by the stepping motor 41 to rotate clockwise in the circumferential direction, the grinding roller 45 continuously rotates anticlockwise under the transmission of the adjusting motor 54 and the gear set, so that stronger grinding force for materials is formed;
compared with the prior art that once the grinding roller 45 loses circular deformation, the grinding roller is replaced, each part of the grinding roller 45 is uniformly stressed, the service life is longer, and the cost is saved;
in order to keep the grinding roller 45 and the external gear 52 connected synchronously, the grinding roller 45 is sleeved from the top of the fixed shaft 44 during installation, the external gear 52 is rotatably installed on the top of the fixed shaft 44, then the fixed shaft 44 is fixed on the top cover 48 in a threaded manner, the fixed shaft 44 of the inverted T-shaped mechanism is matched with the external gear 52 to clamp and lock the grinding roller 45 in the middle, and the detachable installation of the grinding roller 45 is formed; and the wedge-shaped grooves 532 on the end surfaces of the external gear 52 and the grinding roller 45 are correspondingly matched with the wedges 531 to limit the free rotation of the grinding roller 45 on the fixed shaft 44.
